    The technology used to read pencil or pen marks on a multiple choice answer sheet is?

    • OCR

    • OMR

    • POS

    • MICR

    Correct Answer
    A. OMR
    Explanation
    OMR stands for Optical Mark Recognition, which is the technology used to read pencil or pen marks on a multiple choice answer sheet. OMR scanners use optical sensors to detect and interpret the marked areas on the sheet, allowing for automated data capture and analysis. This technology is commonly used in educational institutions for conducting exams and surveys, as well as in various other industries for data collection purposes.

    Hexadecimal has a base value of:

    • 6

    • 8

    • 16

    • 18

    Correct Answer
    A. 16
    Explanation
    Hexadecimal is a number system that uses a base value of 16. This means that it uses 16 different digits to represent numbers, including the digits 0-9 and the letters A-F. Each digit in a hexadecimal number represents a power of 16, starting from the rightmost digit. Therefore, the correct answer is 16.

    An airline reservation system is an example of

    • Batch processing

    • Real time processing

    • Interactive processing

    • Distributed processing

    Correct Answer
    A. Real time processing
    Explanation
    An airline reservation system is an example of real-time processing because it requires immediate response and updates. When a customer makes a reservation, the system needs to check seat availability, process payment, and confirm the booking in real time. Similarly, when a flight is delayed or canceled, the system needs to update the information instantly and notify affected passengers. Real-time processing ensures that the system responds quickly to user actions and provides up-to-date information, making it suitable for time-sensitive operations like airline reservations.

    The MOST suitable device for the output of architectural drawings is a

    • Plotter

    • Laser printer

    • Graphics tablet

    • Light pen

    Correct Answer
    A. Plotter
    Explanation
    A plotter is the most suitable device for the output of architectural drawings because it is designed specifically for producing large-scale, high-quality prints. Plotter printers use pens or inkjet technology to create precise and detailed drawings on large sheets of paper. They are capable of handling the complex line work and intricate details that are often found in architectural drawings. Laser printers, graphics tablets, and light pens are not typically used for architectural drawings as they do not offer the same level of precision and size capabilities as a plotter.

    The decimal equivalent of 00001111 is

    • 8

    • 12

    • 15

    • 25

    Correct Answer
    A. 15
    Explanation
    The decimal equivalent of a binary number can be found by multiplying each digit by its corresponding power of 2 and adding them together. In this case, the binary number 00001111 has four digits. Starting from the right, the first digit is 1, which corresponds to 2^0. The second digit is 1, which corresponds to 2^1. The third digit is 1, which corresponds to 2^2. The fourth digit is also 1, which corresponds to 2^3. Adding these together, we get 1 + 2 + 4 + 8 = 15.

    Which of the following storage media provides sequential access only?

    • Floppy disk

    • Magnetic disk

    • Magnetic tape

    • Optical disk

    Correct Answer
    A. Magnetic tape
    Explanation
    Magnetic tape provides sequential access only. This means that data can only be accessed in a sequential order, starting from the beginning of the tape and moving forward. Unlike other storage media such as floppy disks, magnetic disks, and optical disks, magnetic tape does not allow for random access or direct retrieval of specific data. Instead, it requires the tape to be rewound or fast-forwarded to reach the desired data, making it suitable for long-term storage of large amounts of data that is accessed sequentially.

    Which of the following formatting features is unique to numbers in spreadsheets?

    • Bold

    • Custom

    • Italics

    • Indent

    Correct Answer
    A. Custom
    Explanation
    The formatting feature that is unique to numbers in spreadsheets is "Custom". This feature allows users to apply custom formatting options to numbers, such as adding prefixes or suffixes, specifying decimal places, or using specific date or time formats. It provides flexibility in formatting numbers according to specific requirements or preferences, making it a unique feature for numerical data in spreadsheets.

    Which of the following is NOT a type of transmission medium?

    • Coaxial

    • Twisted pair

    • Modem

    • Microwave

    Correct Answer
    A. Modem
    Explanation
    A modem is not a type of transmission medium. A modem is a device that modulates and demodulates signals to allow digital data to be transmitted over analog communication lines. On the other hand, coaxial, twisted pair, and microwave are all types of transmission mediums. Coaxial is a type of cable that carries high-frequency electrical signals, twisted pair is a type of cable that consists of pairs of twisted wires, and microwave is a type of wireless transmission that uses high-frequency radio waves.

    The pair of files used to produce merged letters during a mail merge is

    • Primary document and data source

    • Primary document and merged letters

    • Data source and merged letters

    • Primary document and current letter

    Correct Answer
    A. Primary document and data source
    Explanation
    During a mail merge, the primary document serves as the template or base for the merged letters, while the data source contains the recipient information that is inserted into the primary document. By combining the primary document and data source, the merged letters are created, which are personalized letters for each recipient. Therefore, the pair of files used to produce merged letters during a mail merge is the primary document and data source.

    Which of the following technologies does NOT facilitate the transferring of data between computers in adjacent buildings?

    • Fibre optic

    • Bluetooth

    • Microwave

    • Twisted pair

    Correct Answer
    A. Microwave
    Explanation
    Microwave technology does not facilitate the transferring of data between computers in adjacent buildings. Microwave communication uses high-frequency radio waves to transmit data wirelessly over short distances. While it is commonly used for communication between devices within the same building or room, it is not suitable for transferring data between adjacent buildings due to its limited range and susceptibility to interference from obstacles like buildings and trees. Fibre optic cables, Bluetooth, and twisted pair cables are all technologies that can be used to transfer data between computers in adjacent buildings.

    A field in a table that appears as a match of the primary key in another table is called a

    • Candidate key

    • Secondary key

    • Foreign key

    • Composite key

    Correct Answer
    A. Foreign key
    Explanation
    A field in a table that appears as a match of the primary key in another table is called a foreign key. This means that the field in question is used to establish a relationship between two tables by referencing the primary key of another table. The purpose of a foreign key is to maintain data integrity and enforce referential integrity between related tables in a database.

    Which of the following is NOT a function of the control unit?

    • Read instructions

    • Interpret instructions

    • Direct operations

    • Execute instructions

    Correct Answer
    A. Execute instructions
    Explanation
    The control unit in a computer is responsible for coordinating and controlling the activities of all the other components. It reads instructions from memory, interprets them to determine the necessary actions, and directs the operations of the other components accordingly. However, executing instructions is not a function of the control unit. This task is typically performed by the arithmetic logic unit (ALU) or other components in the computer system.
